GIMPRQVEMENT IN DUMPlNG- WAGONS.

Specification forming part of Letters Patent N0. 148,108, dated March 3,1874; application filed July 12,1873.

To all whom it may concern:

Be it known that I, CHARLES CAMPBELL, of Cambridge, in the county ofDane and State of Wisconsin, have invented anew and ImprovedDumping-WVagon Box, of which the following is a specification:

The invention will first befnlly described, and then pointed out in theclaims.

Figure 1 is a plan of the bottom of my improved dumping-wagon, and Fig.2 is a longitudinal sectional elevation.

Similar letters of reference indicatecorresponding parts.

A represents the box sides, which are fitted on the bolsters B,in theusual way, and at the rear they are provided with an end board, C. Disthe hind part of the bottom. It is attached to the roller E, suspendedunder the box sides by the cleats F. The front end rests on thecross-bar G, which is fastened to the box sides, and the hind end isheld up by a hook or latch, H, of any approved kind. K represents theend board at the front end of the bottom D, and L the side boards forretaining the front portion of the load when that end rises to dump atthe other end. These parts are arranged so they can be readily taken offwhen not wanted. I represents the hounds of the hind truck, which arefastened to the cross-bar G, instead of the reach, as in the ordinaryarrangement of wagons. J is the fore part of the bottom. It is attachedto the roller M, suspended under the box sides by the cleats N, andrests at the rear end on the reach 0 by the cross-barP. This reach isconnected to the cross-bar G, so as to be detached when the load is tobe discharged to let the hind end of the fore part of the bottom down.The connection is made by a staple, Q, which passes up through the barG, so as to be fastened by a long rod, R, which slides in from the sideof the wagon-box, so that it can be readily put in and taken out. Thisrod passes through the lower portion of a strong partition, S. It issupported by the cross-bar G, so as to sustain the weight of the rearend of the load'upon bottom J, and hold the reach securely. Thepartition S is employed for the end board of the front portion of thebox. It is detacha-bly connected, so that it can be readily removed whenthe wagon is to be used for other purposes. An end board, T, is attachedto the front end of the bottom J, and it may have side boards like thehind bottom,if preferred; but they are not so much needed for it,because the roller on which it oscillatesis near the front end, so thatthe latter does not rise as much as the front end of the hind board doesin consequence of its roller being nearer the hind end. The connectionof the hind and fore parts of the wagon is maintained, when the reachand bottom are disconnected, by the sides A of the box by the roller Nand the front bolster.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. The combination of dumping-bottoms D J, cross-barG, and box sides A, with the rear hounds I, and reach 0, as and for thepurpose described.

2. The combination, with the sides A of the box and the reach 0, of thebottom J, having its rear end supported on the reach, as and for thepurpose specified.

3. The combination, with reach 0 and the sides A of the box, of the barG, staple U, and slide-bolt R, as and for the purpose described.

4. The combination of the detachable end and side board with the bottomI), substantially as specified.

CHARLES CAMPBELL.
